Steffan Donal is a Lead Software Engineer with 11 years of hands-on experience building full-stack and mixed-reality solutions, currently leading engineering at Definely after senior roles at IMRNext and a multi-year stint as CTO and co-founder of LIV. He combines product-minded architecture with practical delivery—shipping client-side SPAs, real-time mixed-reality compositing tools, and automation for scalable deployments and VPS operations. Steffan has a strong front-end focus and accessibility awareness, but also drives backend reliability, ISO-aligned processes, and developer tooling that have saved teams hours of work. He’s equally comfortable founding startups and contributing as an individual developer, and his background in VR broadcasting and live-stream innovation shows a knack for translating cutting-edge tech into engaging, widely accessible experiences.
